We are holding the device firmly on the glass. The glass is not moving.

Excuse me. Why is there a moving object on the Doppler-rabge plot?

How to solve it? use CFAR or static clutter?

Can you try enabling doppler peak grouping? You can also use the doppler filter or static clutter removal if you want to remove moving/nonmoving objects from your detection.

Hi Amanda,

Can you tell me what is causing this phenomenon?

Thanks!

Hello,

It is difficult to know what is causing the phenomenon but it could be that there are multipath reflections from people or objects moving around the sensor.
